Not a taste issue. Current look is horrible and outdated and is optimized for 800x600 resolution which was the norm, say 15? 20? years ago, when CRT was the only thing possible and LCD/plasma displays did not exist. It is not 2000 any more, it is almost 2018. So 800x600 resolution is ancient and obsoleted.
If someone still uses 800x600 as main resolution, they should not use GPU-Z at all and should re-consider what they are even doing using a PC.
I will post another thread on this. Issue is not with the looks so much, as with the badly chosen window size, which is no good any more - we discussed this before too...
